Delaware Unemployment Insurance has decommissioned the Employer Self Service Portal (ESS) as of June 1, 2025. ESS was intended to provide employers with an additional electronic response option, similar to SIDES. However, the platform did not perform as expected and caused significant confusion. Employers should now submit all electronic responses exclusively through SIDES at https://uisides.org/
Minimize the impact unemployment has on the individual, their family, and community.
